File Information

   perm = ONEPERM(N,M) returns the M-th permutation of the sorted list of all permutations from PERMS, where M=1 corresponds to identity permutation. N, M are non-negative scalar, perm has size 1-by-N.
Makes use of a fast algorithm to generate a single permutation.

So not in the same order as Matlab PERMS or C++ STL NEXT_PERMUTATION. I guess this means I can't use this as starting points for a multithreaded version based on STL.
